Will Arnett and Michael Shannon are boarding Jonah Hex, the supernatural-tinged western movie based on the DC Comics character, according to The Hollywood Reporter.
Josh Brolin plays the title character, a scarred bounty hunter tracking a voodoo practitioner (John Malkovich) who wants to raise an army of the undead to liberate the South.
Arnett will play a Union soldier who enlists Hex and is blindsided by the dirty fighting style of his enemies. Shannon plays Doc Cross Williams, the bizarre ringleader of a brutal gladiator circus event.
Production is due to start this month in Louisiana. Jimmy Hayward is directing.
